EDWARD N; MOOR, OF OAKLAND, CALIFORNIA TRAVERSE GRINDING, MILLING, ANDDRILLING MACHINE FOR LATI-IES.

Specification of Letters Patent.

PatentcdSeptQZS,1913.

Application filed January 29, 1913. Serial No. 744,884.

To all whom it may concern Be it known that I, EDWARD N. Moon, a citizenof the United States, residing at Oakland, in the county of Alameda andState of California, have invented certain new and useful Improvementsin Traverse Grinding, Milling, and Drilling Machines for Lathes, ofwhich the following is a specification.

My invention relates to the general class of lathe-attachments, andparticularly to traverse machines adapted for such work as grinding,milling, drilling, etc.

The object of my invention is to provide a rigid, economicallyconstructed and ad justably eflicient traverse machine of this class,and to this end my invention consists in the novel machine and in theconstruct-ion, arrangement and combination of its parts which I shallnow fully describe by reference to the accompanying drawings, in which-Figure 1 is a front elevation of my ma chine. Fig. 2 is an endelevation, partly broken, of thesame, the spindle in the carrier beingomitted. Fig. .3 is a section on the line 02-42 of Fig. 2.

1 is a rigid column which forms the stock of the machine. Through acentral longituclinal bore of said column is fitted a bolt 2, the lowerprojecting end of which is formed with a foot flange 3 and its upperthreaded end is fitted with ,a nut 4: which bears on a cap 5 on the headof the columnstoek. By retelring to Fig. '2 it will be seen that thecolumn-stock is rig-idly clamped to and carried by the lathe-toolpostsupport 6, (.sutficiently indicated in dotted lines) by the foot flange3 of the bolt 2 fitting the slot of said support, and by means of the.nut 4:, clamping the sup, port between said flange and the column foot.Thus the whole machine is firmly clamped to the tool-postswp ort, andmay be readily fitted to lace anremoved; and by reason of the rigidityof the column, the whole device is rigid and stable.

About the column-stock 1 on a spline .or feather 7 thereon, as seen inFigs. 2 and 3, is fitted the split sleeve 8, adapted for accurate linealmovement or adjustment and to be rigidly fixed in the position to vwhich it is adjusted, by means of a bolt 9,

Fig. 3, through its meetin cars 10 at its The sleeve 5 when loosened formovement by relieving its bolt 9, is adjusted with facility andaccuracy, by means of a screw 11. This screw, as seen in Fig. 2, has ahandle 12 on its upper end, said end being seated in a lug 13 projectingfrom the cap 5 of the column stock and fitted with clamping nuts 14. Thescrew 11 is threaded through a nut 15 of the sleeve 8, and its lower.cnd finds a footing in a lug 16 projecting from the foot of the columnstock. In order to define and accurately read the extent of the verticalor lineal adjustment of the sleeve 8, said sleeve is fitted with apointer 17, as shown in Fig. 2, said pointer being itself adjustablycarried in asoeket bearing 18 on the side of the sleeve and securedwhere adjusted by a set screw 19. The pointer 17 coacts with a verticalscale or line of graduations 20 on the column stock to afford thenecessary readings.

The front of the sleeve 8 is formed with a boss 21 having a reducedportion 22, as shown in Fig. 3. Upon this reduced portion' is fitted andadapted to be turned for angular adjustment the annular body 23 of thespindle carrier 24. The carrier body 23 and the reduced portion 22 ofthe sleeve boss 21 have fitted to their faces the gage plate 25 theperipheral edge of which has angle-graduations 26, as seen in Fig. 2. Abolt 27 clamps these several parts together and fixes them rigidly inposition. When the bolt 27 is loosened, the carrier-2 1 may be turned toan angular adjustment, the amount of which is readable on thegraduations 26,. The gage plate 25 is anchored to the boss 21 by ananchor screw 28, shown in Fig. 1, and in dotted lines in Fig. 2.

The spindle carrier 24 is a split sleeve clamped by bolts 29 through itscars 30. In this carrier are mounted the spindle, the bushings, thechucks, the draw-in rod and such other arts as are usual. For the sakeof illustratlon, I show in Fig. 1, the spindle 31, with its belt pulley32, the bushing 33 the chuck 34 with its grinder 35, and the draw-in rod36 with its handle 37. These parts illustrate a grinding machine thoughit must. be understood that for other work, such as milling, drilling,etc., the proper tools will be substituted for the grinder.

38 in Fig. 1 indicates an oil cup connection.

The up er portion of the carrier body '23 is forme with a split bearing39 clamped by bolts 40.' This bearing is used for 'holding devices whichform no part of the present application.
